how do you wrap a tree with christmas lights

The first step is to start with a fresh strand of lights. You can get them from any home improvement store, or you can even make your own. Just make sure that they are rated for outdoor use, so they won't short out in cold weather. Once you have your lights, start at the bottom of the tree and wrap them around the trunk, going up and around the branches. Make sure to overlap the lights slightly as you go, so that the entire tree is covered in a sparkling light display.
